My family lives on the sixth floor, and there is an attic bathroom above. In the evenings and on Sat

It's a leak around the water pipe, and you didn't do a good job of waterproofing it when you renovated the upstairs, so when you use water, it flows down from the floor to the water pipe.

If the water pressure is not enough, you can install a household water pump at the inlet pipe at home by yourself. This is a common problem with old houses. >>>More

You live on the sixth floor, opposite the sixth floor of the community, from the foot is facing your balcony, this doesn't matter, this is no problem.

If the kitchen is not covered with underfloor heating, it has nothing to do with your wool. If there is water vapor, it may also be caused by the temperature of your own house on the 5th floor.

It's good to buy a telescopic staircase, open it when you need it, close it if you don't need it, and it doesn't take up space below, how good, I bought one on Taobao some time ago, my wife and children like it very much, and I said that it was the best thing I bought, oh, I forgot to say, the ladder is from the Oriental Pavilion, the quality is very good, and the boss is super good, haha.
